Compared with legacy, seems the LineAnnotation is not fetching dark mode properly? But I think we should merge in this one and then create an issue to research on it.

It looks like you were able to grab the changes necessary; the PR that fixed this for legacy discover is #4644

[joshuarrrr]

@abbyhu2000 Did you test with the new next theme?

[ashwin-pc]

@joshuarrrr how do you do that?

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/OpenSearch-Dashboards/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/OpenSearch-Dashboards/backport-2.x
# Create a new branch
git switch --create backport/backport-4858-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 89013dad0848567094243bb86de42acd127bc5da
# Push it to GitHub
git push --set-upstream origin backport/backport-4858-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/OpenSearch-Dashboards/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-4858-to-2.x.

You can toggle it in Advanced Settings - just search for "theme"

@abbyhu2000 Did you test with the new next theme?

No i have not, how do we enable the next theme? @joshuarrrr

[joshuarrrr]
